John Quiggin blogs about a slap down of climate change skeptic Ian Plimer that ran in the Australian recently:

In the Oz of all places, a demolition of Ian Plimer so scathing, and so convincing, that it’s hard to imagine how he can salvage any kind of academic reputation, other than by a full retraction (which would be a pretty impressive move, admittedly).

As Plimer seems to be the last person of any credibility denying human-caused climate change in Australia, this has got to be a blow for his supporters.
